Summary: I needed something to fill in the bass that my Polk Audio components simply weren't going to be able to do. I'm sending this 150 watts off a bridged 4 channel amp and am pleased with the sound. I wasn't looking for a huge 'thump', but something to cover the lower frequencies (at a reasonable price). It's doing what I asked it too. The mounting straps are pretty cheesy and cheap, but for the price, I guess that's what you get.
Summary: I have had owned and abused the same bazooka subwoofer in my vehicles since 1990. It has been knocked around and survived 20 new england winters and summers (knock on wood). I've run this thing over and under powered in 4 different systems and it's still thumping.I like my system musically balanced and this sub adds low end presence that you can feel without blowing out the windows.
Summary: I was very surprised on how much bass this 8" bass tube produces. I previously had a 10" Rockford Fosgate Prime in a sealed enclosure pushing a 100 watts rms using old school 2 channel amplifier in a 04 Mazda3 hatchback. This 8" sub out pounds my 10" Rockford sub. When people listen to my car stereo nobody believes that I am using a single 8" sub until I show them. Everyone that listen to my car stereo said it sounds more like a pair of 10" subs or a single 12" sub.
Summary: In the trunk of my 2000 Lincoln Town, 500-watt RMS Kenwood mono sub amp. Is there enough bass?.... yes... but is there more than enough bass?... no (you know what I'm talking about). I was surprised that at only 8" it does a very good job of penetrating through the back seat into the passenger compartment and rounding out the music, but does it produce the super deep bass of my previous sealed Infinity 12" with 1800w peak power handling... no.
Summary: I installed this in the rear area of my S-10 extended cab and it is perfect for what I wanted. As stated before, this won't blow out your neighbors windows or set off car alarms, but it does provide plenty of low end to your system. I am running this Bazooka bridged off a Profile amp. I am very pleased with it so far. The only thing I don't like is the cheap bracket and strap mounting setup, but it is functional and wasn't a big enough deal for me to rate it lower.
